I have mild pain in my left side of scalp and constant heaviness, especially at the evening and night. But when i lie down, it is perfectly okay. But when I am sitting and studying, my right side of scalp feels heavy and there is always a mild pain. And every 30-35 minutes, a sharp pain comes and goes. Recently I had got my blood test done, and everything is fine except my vitamin D. The report shows vitamin D deficiency. I am taking vitamin D supplements since 6 weeks. I have no other symptoms. Also, a point in my upper left scalps hurt when I press on that. I have no pain in forehead, only on left side scalp. Also, my left eye is becoming blurry(I already wear specs (minus 3 power) ) but my eye had started getting blurry since last year only. I am a bit concerned about the headache Please provide guidance Thankyou
